Detailed Implementation
[0016] Reference Appendix Figure 1-5This utility model provides a disk-driven electric tamping machine, which includes a movable frame 107 and a lifting frame 103. The movable frame 107 provides support and drives the entire machine to move along the track. The lifting frame 103 moves up and down relative to the movable frame 107 and drives the working parts (vibrating frame, tamping claw, etc.) to move up and down. The movable frame 107 is provided with movable wheels 111 and a locking part 112 that cooperates with the rail 100. The movable wheels 111 cooperate with the rail 100 to drive the entire machine to move or cooperate with the traveling frame 119 and move indirectly along the rail 100 through the traveling frame 119. The locking part 112 is used to lock the rail 100 during operation, providing a stable force and preventing it from tilting upward due to reaction force. A vibrating frame 104 is fixedly installed below the lifting frame 103, and the lifting frame 103 and the vibrating frame 104 are connected by a shock absorber 114, which is made of rubber. The rubber material serves as a connector and provides shock absorption. Two sets of tamping claws 105 are installed on the vibrating frame 104. Each set of tamping claws 105 has two claws, symmetrically arranged and hinged to the vibrating frame 104. The upper ends of the two tamping claws 105 are hinged to both ends of the clamping cylinder 106. The horizontal relative position of the lower working part of the tamping claw 105 can be changed by the extension and retraction of the clamping cylinder 106, thus facilitating work under the sleepers. The lifting frame 103 and the moving frame 107 are connected by a hydraulic cylinder 116. Specifically, the hydraulic cylinder 116 is a double-headed cylinder. The lower ends of the piston rods 1161 of the double-headed cylinder are fixed to the moving frame 107, and the upper ends of the two cylinders are connected and fixed by a fixing beam 127. The cylinder bodies 1162 of the double-headed cylinder can move synchronously up and down on the piston rods 1161 under hydraulic drive. The two ends of the lifting frame 103 are fixed to the two sets of cylinder bodies 1162 and move up and down.
[0017] Preferably, a rotating shaft 108 is rotatably mounted on the vibration frame 104; one end of the rotating shaft 108 is engaged with the drive motor 123, and the other end is provided with an eccentric wheel 109; the drive motor 123 drives the eccentric wheel 109 to rotate and generate vibration. Preferably, the tamping claw 105 has an upper pick arm sleeve 110 at its upper end. The upper pick arm sleeve 110 is rotatably engaged with the vibrating frame 104, and the tamping claw 105 is inserted into and bolted to the upper pick arm sleeve 110. This structure facilitates the replacement of the tamping claw 105. It also includes an inclined damping rod, with both ends hinged to the two upper pick arm sleeves of each group. The damping rod helps to keep the operation of the two tamping claws consistent (symmetrical), preventing excessive or insufficient movement on one side.
[0018] Preferably, it also includes a battery pack 122, which is disposed on the side of the movable frame 107 and is detachably fitted, such as by bolts or straps. The battery pack is used to provide power to the drive motor, etc.
[0019] Preferably, the drive motor 123 and the hydraulic pump 124 are fixed on the drive motor frame 113, and the drive motor frame 113 and the lifting frame 103 are connected by brackets and bolts and can be detachably fitted.
[0020] Preferably, the drive motor 123 and the rotating shaft 108 are coupled non-contactly via magnetic field coupling. Specifically, a drive disk 101 is mounted on the output shaft of the drive motor 123, and a copper disk 102 is mounted at the end of the rotating shaft 108. A permanent magnet is mounted on the drive disk 101. Driven by the motor, the drive disk 101 rotates, generating a changing magnetic field. The copper disk 102 is passively rotated by the magnetic field, thereby driving the rotating shaft to rotate. The drive disk 101 and the copper disk 102 serve as the active disk and the passive disk, respectively, achieving non-contact transmission and reliable transmission even under conditions of vibration and position changes.
[0021] Preferably, the latching part 112 includes two L-shaped latches 115. The tails of the L-shaped latches 115 are hinged to the movable frame 107, and the heads of the two L-shaped latches 115 are hinged or rotated together via latching shafts, and the heads are clamped to the rail 100. The latching shaft of the head is coupled to the latch seat 117, and the latch seat 117 is coupled to the lifting frame 103 via a tension spring 118. The upper end of the tension spring 118 is fixed to the lifting frame and moves up and down via a bracket, etc., and the lower end is fixed to the latch seat 117. The two ends of the tension spring 118 can be directly fixed to the mating parts or connected and fixed to the mating parts via steel wire ropes, etc. To ensure the effect, it should be kept as vertical as possible. When the lifting frame 103 is lowered, the tension spring 118 is in a relaxed state and is not under force, that is, it does not exert tension on the card seat. At this time, the L-shaped claw 115 is engaged and fixed with the rail 100. When the lifting frame 103 is raised, the tension spring 118 pulls the card seat 117, disengaging the head of the L-shaped claw 115 from the rail 100, releasing the rail 100 from being locked.
[0022] Preferably, the traveling frame 119 includes lower traveling wheels 120 that cooperate with the steel rail 100 and upper rails that cooperate with moving wheels 111. The rails are arranged horizontally perpendicular to the steel rail 100. It also includes locking bolts or locking pins 121 for fixing (or limiting) the moving frame 107. In the working state, the moving frame 107 is fixed to the traveling frame 119 by locking the bolts or locking pins 121, allowing it to remain stationary or move along the steel rail 100 via the traveling wheels 120. When work is finished (during assembly / disassembly), the locking is released, and the moving frame 107 moves out of the working surface of the steel rail 100 along the rail. The traveling frame 119 extends beyond the outer side of the steel rail 100 (the extended portion can be supported by a bracket and is detachable), facilitating the assembly / disassembly or avoidance of the disk-driven electric tamping machine. The main body of the traveling frame 119 spans two steel rails 100, accommodating two sets of the machine, which not only improves work efficiency but also provides balance. The traveling frame 119 is an insulated frame to prevent electrical connection between the two rails 100. This can be achieved by using an insulated component in the middle or by cooperating with the traveling wheels through an insulated wheel seat.
[0023] The working process of this utility model is as follows: Assemble the structure on the traveling frame outside the rail. During operation, place the traveling frame on the rail and move the machine along the traveling frame to the working position above the rail and lock it. Control the hydraulic cylinder to lower the moving frame and the vibrating frame, inserting the tamping claws into the underside of the rail. At this time, the clamping part clamps the rail, and at the same time, the drive motor drives the vibrating frame to vibrate. The tamping claws vibrate while being inserted, and the clamping cylinder can also be used to bring the lower end of the tamping claws close to the bottom of the sleeper to achieve tamping. After completion, raise the moving frame and move to the next position to repeat the above operation.
[0024] In this design, key components such as the battery pack and drive motor can be easily and quickly disassembled. After disassembly, individual components are lightweight, with the heaviest components weighing approximately 100 kg. They can be easily transported and installed manually, making it particularly suitable for locations in the field where large cranes cannot easily access. The traveling frame allows for quick obstacle avoidance without obstructing train passage.
[0025] It should be noted that all connections not detailed in this solution are existing technologies or well-known to those skilled in the art. These include, but are not limited to, electrical connections, hydraulic line connections, and synchronous lifting of hydraulic cylinders.
